PRESERVED MILK.

To all whom it may concern:

Be it known that I, THEODORE B. IVAGNER, a citizen-of the United States, residing at Chicago, in the county of Cookand State of Illino1s, have invented an Improvement in Preserved 'Milk, of which the following is a clear and exact description.

My invention relates to the preparation of a food product obtained from milk and crystallized dextrose, the latter preferably in its anhydrous, form. The new food product thus obtained may be preserved indefinitely and is capable of resisting climatic changes under reasonable conditions and if kept in proper receptacles. It is readily soluble in water, free from obnoxious sweetness, and on standing in a sealed receptacle it does notseparate any solidmatter. My. new product practlcally remains aswholesome as fresh milk, preserving a sweet mllk flavor and, 5

when properly diluted, the natural taste of may vary in its consistency, it may be semisolid or it may be a creamy liquid. The dextrose .to be employed isbest that'kind.

now known under the trade-name of Crystallized anhydrous grape sugar which is the subject matter of my U. S. Patent No. At all events, it must be so pure that it does product.

In carrying out my process practically, I can proceed as follows, the parts given being by weight: I take about 4500 parts of whole milk, heat to approximately 185 degrees Fahrenheit and draw about 3'00 parts of it into a vacuum pan. mainder-of the milk about 650 parts of crystallized anhydrous dextrose and thoroughly not introduce anything which m1 ht counteract the preserving propertles o the dextrose, or change I I then add to the rel Specificationof Letters Patent.

dissolve it by heating and stirring and subsequently draw this also into the vacuum pan. I then evaporate in Wat/L60 at ture of about 1354,40 degrees Fahrenheit, l until the contents reach a density correspondl ing to approximately 31, degrees Baum. I l now allow the contents to cool in the pan .to about 120 degrees Fahrenheit, then break the I vacuum and draw ofi the product into suitable receptacles, in which it is rapidly cooled to about 60 de rees Fahrenheit. If intended for case goo s, the receptacles are subsequently' sealed. Having now described my invention and 4 in what manner the same is to be performed, what I claim as new, and desire to secure by Letters Patent, is:

1. A preserved -milk condensed from a mixture of. milk and crystallized dextrose, free from all other preservatives and free from obnoxious sweetness, readily soluble in water, containing the solid ingredients of milk in substantially the same form in which they are contained in fresh milk and which may be preserved indefinitely and is capable of resisting all climatic changes substan: tially as described.

2. A preserved milk condensed from a mixture of Inilk'and crystallized anhydrous dextrose, free from all other preservatives and freed from obnoxious sweetness, readily dients of milk in substantially the same form in which they are contained in fresh milk and which may be preserved indefinitely and l is capable of resisting all climatic changes 2 substantially as described.

In testimony whereof I have subscribed my name in the presence of two witnesses.
